Superfund: San Antonio, Texas

This week, Hydroviv is highlighting the six new National Priorities List (NPL) sites under the EPA Superfund program. Superfund sites are home to high levels of hazardous soil and groundwater contamination from years of improper disposal techniques. If you’d like to learn more about the ins and out of Superfund, check out our recap HERE. The Superfund site that we’re addressing in this article is located in San Antonio, Texas.

San Antonio, Texas is home to another newly designated Superfund site. EPA detected high levels of cyanide, lead, cadmium, copper, selenium, zinc, chromium, and chromium 6. The source of contamination is from the River City Metal Finishing facility, which was in operation from 1994 to 2002. Throughout operation and post closure, runoff and pollution from this facility entered into the Edwards Aquifer which provides domestic, industrial and agricultural water for a majority of San Antonio. Concentrations of chromium 6 exceeded federal maximum contaminant levels in shallow groundwater wells in the Edwards Aquifer. There are several adverse health effects associated with chromium 6 exposure. Aside from being a known human carcinogen, ingestion of chromium 6 can cause respiratory irritation, pulmonary congestion and edema, and damages to the kidney, liver, and skin. There are currently 20 public water supplies with a 4 mile radius of the San Antonio Superfund site.
